I just had an Exchange Lesson, why can't I add homework for my partner? And why didn't my partner get a level test?

In Exchange Lessons, there will always be one person who is the "learner" for the lesson, and the other person is the "tutor". Level Tests and Homework can only be added for the person who is the "learner" for the lesson.

After the first lesson, you can equally exchange lessons where one full lesson is taught by one person, and then the next entire lesson is taught by the other person. In this case, whoever was the tutor will assign homework and vice versa.

You can also continue to split lessons in half, where half of the session is taught by one person and half by the other. In this case, if you want to assign homework but you were the "learner" for the lesson, you can send a homework file and directions in the chat, or upload it as a lesson material. Unfortunately, at this time, for Exchange Lessons you cannot use the Homework function if you are the "learner" for the lesson, however you can always add it in the subsequent lesson where you will be in the "tutor" role.
